sHlNGLE-GUIDE.

sPEcIFIcATIoN forming part of Letters Patent No. 723,746, dated March 24, 1,903.A g Application filed October 6, 1902. Serial No. 126,103. (No model.)

.To all whom t may concern,.-

Beit known that I, ANDREW SrvnRTsoN, a citizen of the United States, residing at Auburndale, in the county of Wood and State of Wisconsin, have invented certain new and useful Improvements in Shingle-Guides, of which the following is a specification.

My invention relates to shingle-guides; and it consists of a collapsible straight-edge to which is secured a clamping mechanism whereby said straight-edge is held in proper position for Work.

The object of my invention is to dispense with the usual nail-guide land'apparatus 'and produce a guide that is simple, effective, compact, and cheap of manufacture.

A further object of myinvention is to produce a device of this character that is easily and readily attached and detached to and from the work; and with these objectsinview my invention consists of the-parts and combinations of parts, as will be hereinafter more fully set out.

In the drawings, VFigure l is a perspective view of the device in'folded position. Fig. 2 is a top plan view of the same in extended position. Fig. 3 is a side elevation of my invention in use.

1 and 2 are hinged members, preferably pivoted together at their ends, so as to form in open position an elongated guide. These members l and 2 are each provided with a flange 3 at right angles thereto, said anges forming straight edges throughout the length of the device upon which the butt of the shingle may rest. While I have shown lugs 4 and 5 of the respective members 1 and 2 as in merely frictional relation with each other, it is of course obvious to those skilled in the art that I may provide any suitable locking device, such as serrations, whereby the parts may be positively locked in extended or closed position. As the serrations in a joint of this character areold,it is not deemed necessary to illustrate them in the drawings.

6 is a locking-plate provided with an elongated slot 7, in which a bolt Sis secured,said bolt being also secured to the straight-edge member 2. The object of the elongated slot is to adapt said plate 6 for adjustment in or,- der that different weather-s7 may be given to the shingles. The bottom of this plate is .wardly-projecting lugs or ears 1l.

vsomewhat wider than the main body thereof rtially U-shaped clamps on the ends of each vot said arms.

Said plate 6 is provided with an opening 10, on each side of whichare up- 12 is a locking-lever pivoted by means of the pivot 13 in the opening 10 between said ears. The upper end of this lever is provided with an operating-handle 14, while theV lower end is provided with spurs 15, said spurs adapted to be projected when the lever is operated through the opening 10 and into the shingle below said plate, thereby locking the entire device in position.

The operation is as follows: One row ot' shingles having beenlaid, the plate 6 is setto the desired guide by means of the elongated slot 7 and the bolt 8 and the U-shaped fastening-arms 9 pressed over the butt-end of the shingle.v The straight-edge members 1 and 2 having been extended, the lever 12 is pushed upward toward the straight-edge,therebyforcing the spurs into the face of the sh inglre,and inasmuch as the spurs are mounted vandinclined eccentrically to the pivot of the lever they act in the nature ofa cam and draw the U-shaped 'ends of the arms 9 snug against,

the butt-end ofthe shingle, and as they exert a strain opposite to that of the U-shaped arms the whole device is locked securely in position upon the shingle. The next row of shingles is now placed in position and is given the proper gage by merely resting the butt-end upon the straight-edge.

From the above it will be seen that I have produced a very desirable gage of this character.

It will be seen from Fig.y 1 that the members l and 2 are folded togetherand that the plate and locking-lever are slid by means of the elongated slide in' said plate Within the folded portions,so thatthere islvery little projection beyond said members, thusformi'ng a compact and readily-transported tool.

Having thus described m'y-invention, what I claim as new therein, and desire to secure by Letters Patent, is-.

1. In a shingle-gage, the combination with IOO a collapsible straight-edge, of a locking-plate and lever having a slotted connection with said-edge, and constructed to slide and fold substantially within the lines of the Afolded straight-edge.

2. In a shingle-gage, the combination with an elongated straight-edge, of a plate adjustably secured thereto, and having clamps at its bottom edge, adapted to embrace the buttend of a shingle, and a lever connected to said plate and adapted to pierce the shingle and draw the plate up snug! against the buttend of the shingle to lock the plate to the shingle.

3. In a shingle-gage, the combination with two hinged members, and a straight-edge secured at right angles to the top thereof, of a locking-plate provided with an elongated slot,

by means of which it is adjustably secured to one of said members, U-shaped clamps at the bottom of said plate, constructed to engage the butt-end of a shingle, an opening in said plate intermediate the elongated slot and U-shaped clamps, a lever pivoted in p said opening, and spurs secured to the bottom of said lever, constructed to pierce the face of a shingle, and exert pressure in opposition to the U-shaped clamps, whereby the Whole device is firmly secured in position.

In testimony whereof I have affixed my signature in presence of two Witnesses.

ANDREW SIVERTSON.
